Questions & Answers about Am Wochenende bin ich entspannt.
Am is a contraction of an dem.
So am Wochenende literally means “at/on the weekend” (using an + dem in the dative case). German almost always contracts an dem → am in everyday speech and writing.
In time expressions, German uses different prepositions than English:
an (→ am) is used for:
- days of the week: am Montag (on Monday)
- parts of days: am Morgen (in the morning)
- am Wochenende (on/at the weekend)
in (→ im) is used for:
- months: im Januar (in January)
- seasons: im Sommer (in summer)
- years: im Jahr 2020 (in 2020)
So im Wochenende is wrong; German treats the weekend more like a day than like a long period.
